I wonder how many of the muggle-raised students were smart enough to continue their normal education while attending Hogwarts. The magical world seem to have very limited options as far as employment goes, so getting a proper non-magical education is just as, if not more important for their ability to take care of themselves as adults.
Sorry, but I don't catch what you're talking about. Muggle-raised kids don't continue with their normal education while at Hogwarts. They attend Hogwarts. They don't continue with maths and stuff. And being able to care about themselves after school would be just as important to everyone, not just those who are raised by muggles.
But there seems to be a lot of working possibilities even within the wizarding world. You can work within the ministry, and that alone is a wide variety of jobs. Then you can be a healer, a teacher, have a shop, cafe, whatever, really. But really I'm more concerned about their ability to cook and wash their clothes.
